WorkerExtensions.csproj trying to restore from private nuget feed, unsuccessfully

I hope this is the right place for this question.

I have this recurring problem with our local Functions app trying to build. We recently moved to .NET 6 Isolated to support some future product features.

On build, I get this error:

1>C:\Program Files\Microsoft Visual Studio\2022\Professional\Common7\IDE\CommonExtensions\Microsoft\NuGet\NuGet.targets(132,5): warning : No Authorization header detected
1>Retrying 'FindPackagesByIdAsync' for source 'https://nuget.pkg.github.com/{{ ourorg }}/download/microsoft.azure.webjobs.extensions.durabletask/index.json'.
1>Response status code does not indicate success: 401 (Unauthorized).

1>Failed to restore C:\Users\kevin\AppData\Local\Temp\l20wov0k.lk5\WorkerExtensions.csproj (in 5.86 sec).

I’m not sure why WorkerExtensions.csproj is trying to look at our private Nuget feed for that package.

Functions.csproj
